Calciothermic reduction of titanium dioxide is suggested as an alternative to the conventional Kroll process for production of metallic titanium. In this study, a simple reactor was used to carry out the reaction of TiO2 with 20 wt % excess Ca at 1000°C to obtain titanium product with a mean size of Ti particles around 20 μm. A sharp decrease in reaction temperature can be achieved by using KClO4...
